14×1 LH CONFIGURATION
Designed around traditional 14×1 LH AK-pattern muzzle threads and optimized for 7.62×39.
The three-sided port layout eliminates the need to rotationally time the brake, while the muzzle-face mounting system provides a defined indexing surface designed with suppressor alignment in mind.
Rather than adapting an AR-style mounting solution to the AK platform, The Sickle was built around the geometry of the AK muzzle from the start.
No timing. Purpose built for the AK.
Frequently asked questions
What was The Sickle designed to do?
The Hammer was built around a simple idea:
The Sickle takes the core principles of The Hammer and redesigns them specifically around the AK platform.
Its three-sided port geometry was engineered to reduce recoil and muzzle movement without requiring rotational timing, while the face-mount architecture provides a more defined indexing surface for suppressor use on 14×1 LH AK platforms.
That mounting system was chosen with suppressor alignment in mind, helping reduce the conditions that can contribute to baffle or end-cap strikes on platforms where muzzle geometry and thread concentricity can vary.
The Sickle also retains a common-bore architecture intended to support multiple compatible calibers and incorporates a Plan B-compatible suppressor interface, allowing it to function as both a standalone muzzle brake and suppressor host.

What calibers is The Sickle designed to support?
The Sickle utilizes a common-bore architecture designed to support a range of compatible AK-pattern host applications.
Its port geometry is optimized around 7.62×39, while maintaining broader caliber flexibility.
Current intended applications include:
7.62×39
5.45×39
5.56 NATO / .223 Remington
9mm
7.62×54R
Compatibility depends on more than caliber alone. Always confirm the host’s thread pattern, bore alignment, projectile diameter, and suppressor or mounting-system requirements before installation.
Is The Hammer Plan B compatible?
Yes.
The Sickle is designed around the Plan B mounting interface for use with compatible suppressors, adapters, and mounting systems.
The muzzle-face mounting architecture was also developed with suppressor use in mind, providing a defined indexing surface on 14×1 LH AK platforms.
Always verify compatibility and alignment with the specific suppressor, adapter, and manufacturer requirements being used.
What thread patterns are available?
The Sickle is currently offered exclusively in 14×1 LH, purpose-built around traditional AK-pattern muzzle threads.
For 1/2×28 applications, check out The Hammer Brake.
Does The Sickle require timing?
No.
The Sickle uses a three-sided port design that eliminates the need to rotationally time the muzzle device.
The face-mount architecture allows the brake to install without indexing to a specific orientation, while still maintaining the port geometry needed for recoil and muzzle control.
Thread it on. Torque it down. Run it.
Why does The Sickle use a face-mount design?
The Sickle uses a muzzle-face mounting system because it was designed with suppressor use on the AK platform in mind.
Many 14×1 LH AK barrels don’t provide the same clean, consistent shoulder commonly found on other suppressor-host platforms. Indexing from the muzzle face gives The Sickle a defined mounting surface for the brake and Plan B suppressor interface.
The goal is a cleaner, more consistent mounting solution on a platform where suppressor alignment matters.
Does The Sickle use the AK front-sight detent?
No.
The Sickle does not rely on the AK front-sight detent for timing or indexing.
Its three-sided port geometry eliminates the need for a specific rotational orientation, while the muzzle-face mounting system provides the reference surface for installation.
The result is a cleaner mounting system designed specifically around the AK platform.
Should suppressor alignment be checked after installation?
Yes.
Suppressor alignment should always be verified before firing whenever The Sickle is used as a suppressor mount.
PW Labs recommends checking alignment with the appropriate alignment rod after installation and whenever the muzzle device, suppressor, adapter, or barrel configuration changes.
Do not fire the system if alignment is uncertain or if the suppressor contacts the alignment rod.
Will all of the muzzle threads be covered after installation?
Not necessarily.
The Sickle indexes from the muzzle face, not the front-sight block. Because thread length can vary between AK manufacturers and individual barrels, some 14×1 LH threads may remain visible behind the brake once it is fully seated.
That does not indicate improper installation.
The important point is that The Sickle is fully seated against the muzzle face and installed according to the supplied instructions.
Is The Sickle made in the USA?
Yes.
Every Sickle Brake is manufactured in the United States from domestically machined 17-4 stainless steel.
